I have a LSE7806ACE stackable washer and dryer. The dryer is not throwing any heat and the agitator quit working at the same time.

WASHER WILL NOT START:
Power If your washing machine won't start, begin by looking at the power source. First of all, is the washing machine plugged in? If it is, has it tripped a circuit breaker or blown a fuse? Check and reset the breaker (or replace the fuse) if necessary.

Lid Switch The main control for the washing machine is the switch inside the lid. If this has stopped working for some reason, your washing machine won't start. It's not especially difficult to troubleshoot this on a washing machine. You might have to open the top to access the switch. With the power on, depress the switch and listen for a click. If you don't hear one, the switch MAY BE BAD and will need to be replaced. Confirm defectiveness with a multi meter checking for continuity OHMS. An open circuit reflects a bad switch..
If the switch works but the washing machine still won't start, check to see if your washing machine has a special fuse for the lid switch. It will usually be inside the control panel. If it's blown, you'll need to replace it before the washing machine will start.

Door Interlock The problem could be with the door interlock. If the lights come on but the machine won't start, this might well be the cause. This could either be down to the wiring that runs to the door interlock, or the door catch not activating the interlock itself.

Timer Knob Some models of washing machine use a mechanical timer knob and won't run until the water in the machine has filled to the selected level. If the knob doesn't line up properly with the graphics on the control panel, you can try to troubleshoot the washing machine problem by advancing the timer a little. When you've done this, pull it out a little way and see if the washing machine will start properly.

Push start switch may need to be tested with a multi meter for continuity OHMS should show a closed circuit when pushed in or turned on.
The start switch on some top load washers is often part of the timer and is activated by pulling out on the timer knob. Although not normally available as a separate part, the switch can be tested for continuity with a multi-meter. You will need to remove power from the appliance and then locate the correct timer contacts as noted on the wiring diagram. On some electronic controlled models, the start switch is a momentary contact type switch located on the control console. You can test this switch for continuity with a multi-meter when the push button is held in


Overheating If you've run several loads, one after another, without any problem but suddenly find your washing machine refuses to start, overheating could be the cause. The simple way to discover whether this is the problem is to give the machine ample time to cool down, say for a couple of hours, and then try it again. If it works fine, overheating has been the problem and you may have a motor with bad windings.
By the way my advice is free cuz God is good!

All washing machines use a motor that is responsible for spinning and agitating during the cleaning cycle. Many top load brands use a reversing motor which means the motor spins in one direction for agitating and another for spinning and draining. If the motor does not start, but makes a humming or buzzing noise then it may be defective. To verify if the motor is at fault, remove the drive and /or pump belts and then try to start the motor again. On direct drive models, you will have to disengage the pump and the direct drive coupling to the transmission. If the motor starts, then the problem is with the transmission or the pump and can be further diagnosed by reconnecting each one individually. If the motor does not start or continues to hum or buzz, then it will need to be replaced
Lastly CONTROL BOARD
If the control board does not provide the proper voltage to the drive motor, fill valve, drain motor or door lock then the washer may not start. The main control board on most washers is complicated and difficult to diagnose without proper test equipment and procedures. You can visually inspect the control for signs of electrical arcing or burned or damaged components on the board. You should use caution when replacing a control board as sometimes the burned components are caused by external component failures.

ELECTRIC Dryer no heat or little heat, or shuts down to fast:
Check your venting and lint basket.Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity it should show OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or
overheating.

The heating elements are located inside the heater ducts. If you think a heating element is faulty, test it with avolt-ohm-multimeter (VOM)set to the RX1 scale at 20K ohms. Disconnect the leads from the power terminals and clip one probe of the VOM to each terminal. The meter should read about 12. (1200) ohms. If the reading is higher ohms, the heater is faulty and should be replaced. Replace a faulty heater with a new one of the same type and electrical rating. A heater connected to a 115-volt line usually has an 8.4-ohm resistance; a heater connected to a 220-volt line usually has 11 ohms resistance.


Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

OR you may have a broken centrifugal switch in the motor because this switch activates the motor and the heater as well. supposed to be if the motor does not run, the heater should not heat in order not to create a fire but if the motor is not running, and the heater is still heating, then there could be a problem with the motor centrifugal switch that is connected to this interlock switch that should trigger the heater.

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum this is why in some cases the dryer will operate at lower cycles like gentle or low heat but not at higher settings?)

Lastly check your moister sensor. ( located inside the dryer door usually)Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.
